The more direct test being
sapply(c(a=1,b=2), names)
Problem:
R ("all" versions)
behaves the same as S+5.1, which is wrong IMO.

I do. the argument is not a list, and lapply applies to lists. So
as.list(c(a=1,b=2))
$a [1] 1 $b [1] 2 Fine. Note the names of the components are NULL.

z <- c("a"=1, "b"=2)
lapply(z, function(x)names(x))
$a: [1] "a" $b: [1] "b" But in S-PLUS 5.1 (Linux),
z <- c("a"=1, "b"=2)
lapply(z, function(x)names(x))
$a: NULL $b: NULL Is this a new feature of S-PLUS 5? Do I miss anything in S-PLUS 5?
